“…However, these values are still within normal ranges. On contrary of the present results, Khatibjoo et al (2017) reported that supplementing MCFA to broiler's diet resulted in significantly increased and decreased percentages of heterophils and lymphocytes, respectively. Some blood hematological values (Hb and RBCs) did not significantly affected by feeding different CO levels in duckling,s diets.…”

“…Lymphatic organs: Data in Table 4 showed that spleen and thymus indexes significantly (P≤0.05) increased in treated groups compared to control one. These results are in disagreement with findings of Khatibjoo et al (2017) that showed that dietary MCFA addition to broiler's diet did not significantly influenced spleen and thymus weight. The main immune organ such as thymus and spleen as secondary immune organ in avian species perform greatly significant roles in immunity of birds, including the main local sites for the maturation, differentiation and proliferation of lymphocytes.…”

This study aimed to determine the effect of dietary supplementation of coconut oil levels on some physiological and immunological responses in ducklings during growing period (28-89 day of age). A total number of 120 Domyati ducklings, 28-day old were used, weighted 530-545 g and divided into four experimental groups, each of three replicates to determine the effects of feeding diets contained different levels of coconut oil (CO) as a medium chain fatty acids (MCFA) source. The experimental groups were arranged as follows: The first as a control group (G1) which received basal diet without any supplementation, while the second, third and fourth groups (G2, G3 and G4) were received diet contained CO by 1.0, 1.5 and 2.0 %, respectively. The results revealed that, percentages of heterophils and lymphocytes were significantly (P≤0.01) lower and higher, respectively, for Domyati ducklings in G4 than those in the control group (G1). Some blood hematological values (Hb and RBCs) did not significantly affected by different CO levels. The ratio of hetrophil to lymphocytes (H/L) was significantly (P≤0.01) lower for Domyati ducklings in G2 and G4 than those in G1. Spleen and thymus indexes were significantly (P≤0.05) increased in treated groups compared to the control one. Moreover, dietary CO levels caused to increase the values of plasma IgG, IgM and IgA concentrations than that of the control group. The different dietary levels of CO significantly influence the lipid peroxidation (LPO) by decreasing MDA values. Conclusively, ducklings fed diet supplemented with 1.5 or 2% CO had heavy immune organs weights, and high plasma levels of immunoglobulins, which collectively suggested as an improvement in the immune response.

“…Concerning the treatment effect on abdominal fat%, chicks fed diets supplemented with 0.05% MOL or the control showed higher values (1.11%), while, chicks fed 0.08% MOL or 0.08% MOL+ 0.1% MCFAs showed lower values (0.85 and 0.90%, respectively) and the differences were insignificant (Table 3). These results indicate that there were no statistically significant differences in some carcass quality between the control and trial groups in other parameters which is similar to the findings of Khatibjoo et al (2018). In this respect, Aderinola et al (2013) observed that the proportion of abdominal fat decreased as the inclusion level of MOL increased.…”

“…Results from more recent research in broiler chickens are not uniformly in agreement with our research. For example, Khatibjoo et al (2018) reported that broilers fed diet containing MCFAs had worst FCR. Along with this similar results, Adil et al (2011) found supplementation of 0.2% or 0.3% acidifier had no effect on FI than those without acidifier.…”

total number of 300 one-day old unsexed Cobb broiler chickens were initially fed a control diet for six days, then were into ten treatments, each treatment contained three replicates of ten birds. The objectives were to determine the effects of single or combined supplementation of Moringa olivera leaf meal (MOL) and medium chain fatty acids (MCFAs) to broiler diets on productive performance. The experimental treatments were as follows: 1-Chicks were fed the control diet (D 1), 2-D 1 + 0.5g MOL/kg diet, 3-D 1 + 0.6g MOL/kg diet, 4-D 1 + 0.7 g MOL/kg diet, 5-D 1 + 0.8g MOL/kg diet, 6-D 1 + 1 g aromabiotic /kg diet, 7-D 1 + 1g aromabiotic/kg diet + 0.5g MOL/kg diet, 8-D 1 + 1g aromabiotic/kg diet + 0.6g MOL/kg diet, 9-D 1 + 1g aromabiotic /kg diet + 0.7g MOL/kg diet, and 10-D 1 + 1g aromabiotic/kg diet + 0.8g MOL/kg diet. Results obtained could be summarized in the following: Chicks fed combined supplementation of 0.08% MOL +0.1% MCFAs had significantly higher live body weight at 38 day of age and body weight gain during the period from 7-38 days as compared with the control or other treatments. Also, these birds had the best significantly values of feed conversion ratio, crude protein conversion, caloric conversion ratio and higher growth rate, performance index, economical and relative efficiency during the period from 7 to 38 days compared with the control. No significant differences were noticed in slaughter parameters and immune organs% as affected by the treated groups in comparison with the control. Chicks fed diets supplemented with 0.08% MOL+ 0.1% MCFAs or 0.07% MOL+ 0.1% MCFAs had significantly higher values of white blood cells, lymphocyte (L) and H/L ratio (lower value of heterophils (H)). The level of serum aspartate aminotransferase and total cholesterol had decreased significantly in chicks fed diets supplemented with MOL plus MCFAs compared with the birds fed control or some MOL diets. The highest values (significant) of total count, lactobacillus count and immune response to Newcastle disease were recorded for chicks fed diet supplemented with 0.08% MOL +0.1% MCFAs. E.coli counts were reduced significantly by feeding all treated diets compared with the control.

“…As to serum cholesterol, perplexed results were emerged from this study. It is reported that fats rich in medium-chain vs. long-chain fatty acids are known to decrease total or HDL cholesterol in chickens ( Wang et al., 2015 , Khatibjoo et al., 2018 ). In contrast, we found that total and HDL cholesterol was higher by on average 31.8 and 27.0% in coconut oil–fed chickens than corn-oil fed ones.…”

The present study was conducted to investigate growth performance, carcass characteristics, short-chain fatty acids, fatty acid composition in abdominal fat, and serum parameters in broiler chickens fed diets containing corn oil, coconut oil, or black soldier fly larvae ( BSFL ) oil at the level of 50 g per kg of diet during the 30-day-feeding period. A total 450 one-day-old male broiler chicks (Ross 308) were randomly allocated to one of 3 dietary groups. Each treatment had 10 replicates with 15 chicks per replicate. Feed conversion ratio was decreased in the coconut and BSFL oil group compared with the corn oil group. Dietary BSFL oil increased ileal weight-to-length ratio at day 30 after hatch. Dietary BSFL oil increased significantly ileal branched-chain fatty acid ( P < 0.05) and moderately total short-chain fatty acid in 15-day-old broilers ( P = 0.074). At day 30, ileal propionate was highest in the coconut oil group but cecal propionate was highest ( P < 0.05) in the BSFL oil group. Fatty acid composition of abdominal fat was affected by dietary fat sources. Especially, chickens fed diets containing coconut oil or BSFL oil had higher contents ( P < 0.05) of saturated fatty acid being dominant in lauric and myristic acids compared with those fed on corn oil. On the other hand, the reverse trend was noted ( P < 0.05) as to polyunsaturated fatty acids being dominant in corn oil compared with coconut oil and BSFL oil. Coconut oil vs. corn oil significantly increased total and high-density lipoprotein cholesterol. Finally, BSFL oil vs. corn oil significantly increased total antioxidant capacity in chickens. It is concluded that dietary BSFL oil improves feed conversion ratio and increases the incorporation of medium-chain fatty acids into abdominal fat pad and serum antioxidant capacity in broiler chickens.
